Biohythane (biohydrogen + biomethane) from lignocellulosic biomass is a win — win solution for the supply of renewable energy and valorization of organic wastes. Lignocellulosic biomass contents mainly lignin, cellulose and hemicellulose. The carbohydrate contains is approximately 70–80% (w/w) of the total biomass. These carbohydrates can be suitable raw material for dark fermentative biohydrogen...
A customized 20 L airlift photobioreactor was utilized for the growth of Chlorella sp. MJ 11/11. The biomass obtained was further used for production of biodiesel. A one step transesterification process was utilized for the production of biodiesel from algal lipids. The lipid content of Chlorella sp. MJ 11/11 was determined to be 58% w/w. The biomass obtained was flocculated using chitosan (stock...
Dark fermentative effluents were used as substrates in Microbial fuel cells (MFCs) and the power outputs of MFCs were improved by optimization of influential anodic operational parameters. An initial power density of 1.4 W/m3 was obtained by an enriched mixed electrogenic which was further increased to 5.43 W/m3 by optimization of influential anodic parameters. By utilizing various dark fermentative...
Wild type ethanologenic microorganisms display very low ethanol yields on xylose in lignocellulosic hydrolysate due to low tolerance to ethanol and other metabolic inhibitors present in hydrolysates. The major thrust of research on xylose conversion has been towards the development of recombinant microorganisms capable of simultaneous uptake of glucose and xylose. These genetically modified ethanologenic...
Batteries are used as power storage device in solar photovoltaic (PV) systems. They supply power when there is no solar power generation in the absence of sunlight. Charge controllers are used to charge the batteries safely following the proper charge procedure and an efficient charge controller should have the ability to extract as much power as possible from PV module to charge the batteries. This...
With the gradual increase in population and increased use of modern machinery, the power demand is always on the rise. Any power network has the ability to cater to a specific maximum volume of load. Increase in load demand makes the system weaker and thus, the power system tends to work under stressed conditions. Increase in system load above a certain threshold may result in cascaded voltage collapse...
Silver nanoparticles are often used as optical resonator or scatterer in different opto-electrical devices. But being a metal, high ohmic loss will occur because absorption and scattering both peaks arises at the same resonating frequency. To overcome this limitation, separation of absorption peak and scattering peak is very much needed. So in this work we present a method using metamaterial incorporating...
Enhancing the light absorption in ultra-thin crystalline silicon wafer based solar cell is a challenge to be met. Among several approaches and techniques to do so, the very simple yet effective technique of lensing the light into the substrate is investigated in this work. Spherical silica micro-lenses have been designed and studied. The effect of the micro-lenses has been observed for varying substrate...
By considering the limitation of the conventional energy resources, renewable energy plays an important role today. The agriculture procedure is totally dependent on the good irrigation process and the irrigation process is on the energy sources. Solar photovoltaic pumping can provide the necessary alternative way. With the advancement of the technology, so many pumps are available in the market which...
In this present work focused on combination of two different biodiesel blends with diesel. The present study brings out an experiment of two bio diesels from jatropha oil (B20J), Mahua oil (B20M) and Dual biodiesel(B10M+B10J) they are blended with diesel. The effects of dual biodiesel works in engine and exhaust emissions were examined in a single cylinder, direct injection, air cooled and high speed...
Present Wind mills have certain limiting factors. Most of the wind farms are located quiet far from the power utilizing areas; Monitoring and controlling of such farms are very tedious. Wind farms may be located far inside the sea, may be between the mountains, or Forests. Thus when minor faults occur, the people have to go to that particular location for fault clearing. It requires lot of man power,...
Govt. of India scaled up of budget during 12th five year plan for Rooftop solar project to achieve the target of 40 GWp as committed before UNFCC (United Nations Framework Convention on Climate Change). In this connection through a case study it is shown that there is a chance to reduce the target and also the space of solar project installation if a manual solar tracking based on optimum tilt angle...
Linear Fresnel Collector (LFC) consists of parallel reflector rows on a horizontal plane that reflects the incident solar radiation on to a common focal plane. Receiver positioned at the common focal plane absorbs the reflected solar radiation. As the Sun's position in sky changes throughout the day and year, portion of reflected rays that reach the absorber varies. Fraction of absorber area remains...
Rise in energy demands and the need to curb carbon emissions has made proliferation of conventional fuels unviable, leading towards the search for alternative energy sources. With a surplus of sunlight reaching the earth every day, solar energy is an immediate renewable alternative to be considered for satisfying the end-user demand requirements. However, generation using solar energy poses its own...
As the demand of time is cost reduction of solar photovoltaic power generation by reducing the active material usage, the unique micro-nanostructure geometry reported can effectively achieve this goal by reducing approximately 50% material usage. Analysis and optimization of the nanostructured geometry is presented in this work. The results are also compared with conventional textured silicon solar...
In recent years, the significance of distributed generation has increased rapidly in distribution system. The prominent goal of DG placement is to measure the optimized location, type and sizes of DGs for getting best efficiency by maximizing or minimizing different constraints. This work investigates the recent research in the field of Swarm intelligence based optimal DG placement. Swarm intelligence...
Growing energy needs and the depleting nature of the nonrenewable sources demand the intervention of renewable sources and storage technologies which are sustainable. It is therefore desirable to perform sustainability analysis in terms of energy efficiency for electrochemical storage systems. This paper is concerned with life cycle energy analysis of batteries used for photovoltaic application in...
In recent years, the majority of the research has focused on grid-tied transformerless PV inverters, more capable than traditional grid-tied line transformer-based PV inverters, but more critical from a power quality point of view, especially in terms of common mode voltage and ground leakage current. Neutral point clamped (NPC) converters have recently gained popularity due to high efficiency and...
